=== Notes and Comments ===

* Some files and the directory are compressed using zlib
* Filetype Identifiers:
** 0 - Uncompressed file
** 1 - Compressed file
** 256 - Directory
* Initial value for the CRC32 Checksums is 0
* The encryption algorithm is a modified TEA version (it has the same characteristic bitshifts)
** There exists multiple versions of the same algorithm but with different 128-bit keys and different deltas
** The Encryption Identifier will tell you which algorithm to use
* The hashfunction for the filenames is crc32()
* The Timestamp is the Windows FILETIME struct

==== Encryption Table ====

The data of some files may be compressed or encrypted. The Encryption Table maps the Filetype Identifier
to an algorithm that can handle the data. The table has 8 available slots. The Filetype Identifier 0 is
mapped to slot 0, Filetype Identifier 1 is mapped to slot 1 and so on...

If a slot is null, the data is neither compressed nor encrypted. Otherwise the slot contains an
Encryption Identifier that tells you how to handle the data.

Example: We have a file with File Type Identifier 1. We look at slot 1 of the encryption table and will find
the value: 0x9BB3F065. This tells us that we have a file that is compressed and that the first 16 Bytes
of the filedata are encrypted with a simple XOR-algorithm.

'''shrlsnd0.bba''' contains 3 mp3s performed by the Viking character Thordal in game as his special power. So far i've been able to extract 64 mp3's with success from this archive, but after that, I keep getting 1 good frame, and then rubbish, and this pattern keeps repeating. I have also found some unencrypted/uncompressed PCM Wave headers (RIFF & fmt tags), so I'll try to put that in the mix to get a better picture of the archive composition. The linked script above extracts the 3 mp3s from Throdal.
